8/1 Carlos Silva update

Carlos Silva was pulled from Sunday’s game in the first inning because of an abnormal heart rate and he was taken to a local hospital where he will remain overnight for evaluation.

Dexter Fowler flew out to center to start the Rockies’ first and Silva then walked Jonathan Herrera. Cubs pitching coach Larry Rothschild and assistant athletic trainer Ed Halbur went to the mound to check on the right-hander, but he stayed in the game.

“They thought it was just the altitude,” Cubs acting manager Alan Trammell said.

Silva initially complained about having difficulty breathing.

Carlos Gonzalez then singled and Troy Tulowitski hit a ground-rule RBI double, and catcher Geovany Soto signaled to the Cubs’ dugout. Rothschild and head athletic trainer Mark O’Neal then went to the mound and Silva was pulled.

“I went out to him and said, ‘Are you all right?'” Soto said. “He said, ‘Yes, my heart’s racing a little bit.’ He was making funny faces and I went back and said, ‘What’s wrong?’ He said, ‘My heart’s racing.’ I called down [to the dugout].

“[Silva] said, ‘I don’t want to come out of this game,'” Soto said. “But that’s not a finger or a muscle. You’ve got to take care of that. It’s the ticker. You’ve got to be careful.”

Silva had an extremely high pulse and paramedics diagnosed it as PSVT (paroxysmal supraventricular tachycardia), which is an abnormal heart rate. It was corrected as the right-hander was taken to the St. Jospeph’s Hospital, where he will remain overnight.
